vascular plants Group of plants having lignified conducting tissue (xylem vessels or tracheids).

vascular plants
Plants with vascular tissue, consisting of all modern species except the mosses and their relatives.
vascular tissue ...

nonvascular plants Plants lacking lignified vascular tissue (xylem), vascularized leaves, and having a free-living, photosynthetic gametophyte stage that dominates the life cycle. Common examples are the mosses and liverworts.

In vascular plants, the xylem is the tissue that carries water up the root and stem. In trees, it constitutes wood; the word is derived from Greek ξύλον xúlon, "wood, timber".

xylem In vascular plants, the tissue that conducts water and minerals; xylem consists, in various plants, of tracheids, vessel members, fibers, and parenchyma.

Cryptogams: nonvascular plants such as lichens and mosses that make up the ground or surface layer of vegetation.

The more primitive plants are dependent on living in water either totally or partially and the more advanced vascular plants have found ways to live independently on land.

Vascular plants are considered to be more advanced than nonvascular plants because they have evolved specialized tissues, namely xylem, which is involved in structural support and water conduction, and phloem, ...

The plants we discuss will be vascular plants that have systems of tubes (xylem and phloem) for the transport of nutrients and water.

Vascular plants can be divided into seedless (ex. ferns) and seeded. Vascular seeded plants can be divided into gymnosperms (ex. pines) and flowering plants (angiosperms). Angiosperms can be divided into monocots and dicots.

If you look at a single acre of prairie, you'll find about 200 species of flowering and other vascular plants in it. If you look in the soil, you'll find at least 5,000 different species of bacteria, probably a thousand or so species of fungi.

A superclass in the sperm plants (Spermatophyta) division belonging to the vascular plants (Tracheophyta) phylum of the plant kingdom.

But in all other vascular plants, this region is inverted and the order of the genes is precisely reversed. This provides further evidence that the other vascular plants we shall examine below, the ...

leaf -- An organ found in most vascular plants; it consists of a flat lamina (blade) and a petiole (stalk). Many flowering plants have additionally a pair of small stipules near the base of the petiole.

transfer of soluble materials through the sieve tubes of the phloem of vascular plants; the exchange of parts of chromosomes

cambium - a thin formative layer between the xylem and phloem of most vascular plants that gives rise to new cells and is responsible for secondary growth (Merriam-Webster) ...

vascular bundle
A structure of vascular plants that runs up through the roots, into the stems, and out into the leaves, and whose function is transport of water, ions and dissolved organic solutes within the plant.

stele. The central cylinder inside the cortex of the roots and stems of vascular plants; contains the vascular or conducting tissue.

Eutrophication: Enrichment of a water body with nutrients, resulting in excessive growth of phytoplankton, seaweeds, or vascular plants, and often depletion of oxygen.

Water has the ability for capillary action, the tendency to move up a narrow tube against gravity, a property relied upon by vascular plants, such as trees.
